I'm trying to upgrade from 1.9 final to 1.9.2 beta 3 on Unity 4.1.0f4.
If I try to import the new version while the old one still exists, I get a bunch of errors about imported types being defined multiple times.
I tried rebuilding the project index, but that seems to completely break everything. Specifically, the 2dtoolkit menu gets reduced to just "Setup for Javascript" with no other menu items & I can no longer create any 2dtoolkit components. It breaks so badly that I have to restore the project from a backup.
Is there a more correct method for upgrading the 2dtk package? If I delete it first, won't that break all of my existing sprites?
